CFNM is an abbreviation of Clothed female, naked male. It is an activity featuring one or more nude men and one or more clothed women.

Commonly it would involve one naked sub male and a number of dominant clothed females, the idea being that the sub male would feel humiliated by the experience, in that he is not permitted to wear clothes and his lack of clothing places his status below that of the clothed females.

This kind of activity often takes place in public humiliation or vanilla audience play.

The naked sub male does not have to be entirely naked for a scene to qualify as a CFNM scene. Commonly a 'naked' sub male would wear a collar or even women's panties.
